Analyzes ERC-4337 account abstraction adoption trends on Base, tracking UserOperation counts, bundler market share, paymaster utilization rates, and smart wallet deployment velocity over time. Identifies which account abstraction use cases are achieving genuine product-market fit beyond developer experimentation based on repeat user behavior and sustained transaction volume trends. Publishes monthly account abstraction growth reports as verifiable on-chain attestations with protocol-level adoption breakdown and retention metrics.
